Swift Scirocco in 300 Win. and 3006
 

I am trying to find info on loading the 180 gr. in 300 Win. and the 165 in 3006. The company won't release any load data. I'm ready to start loading. I am wondering if the pure copper jacket makes it like the X bullet or if there is enough lead there to allow it to slug up in the barrel like a conventional bullet. If so then I can start with conventional data. Any experiences or reports appreciated.
